Laboratory statistics and measurement reporting guides
Work through repeated measurements, reporting limits and uncertainty so a colleague can tell what a result means and how it was obtained.
What Replicate Measurements Tell You About Precision and Trueness
Compare repeat injections with independent preparations. Calculate the sample standard deviation and document any difference from an assigned reference.
Not Detected vs. Below LOQ: How to Record Laboratory Results
Interpret LOD, LOQ and laboratory qualifiers, with examples of dilution, differing limits and data entry.
How to Report Expanded Measurement Uncertainty (with a Worked Example)
Identify the measurand, distinguish standard and expanded uncertainty, and apply the stated decision rule.
